Michael Jackson's Doctor Conrad Murray Trial Day 7: Jackson's Slurred and Incoherent Speech Reveals Singer Wanted to Open Children's Hospital (PHOTOS+VIDEO)

A recording of Michael Jackson's slurred and incoherent speech was played in court on Wednesday, Oct. 5, as the involuntary manslaughter trial of Jackson's doctor Conrad Murray entered the seventh day.

The recording, which was retrieved from Murray's iPhone, is a phone conversation between Jackson and Murray, dated May 10, 2009.

I'm gonna do that for them. That will be remembered more than my performances, the King of Pop's voice, obviously slurred and incoherent, rambled about his intention to open a children's hospital.

I love [children] because I didn't have a childhood. I feel their pain. I feel their hurt, he continued.

However, there's a long halt toward the end of recording. After that, Murray asked, You OK?

I am asleep, Jackson replied with barely coherent speech.

Sally Hirschberg, a medical supply representative, took to the stand. Hirschberg was in charge of order records at Seacoast Medical supply company, where Murray ordered some powerful drugs.

Hirschberg testified that Murray's office in Las Vegas had ordered some equipment and drugs to a California residential address, not a medical facility, which raised a red flag initially for her.

According to Hirschberg, it's unusual for a cardiology clinic to order the powerful drugs such as Lidocaine, a common local anesthetic, and IV bags.

However, on June 26, 2009, the day after Jackson died, a call from Murray's Las Vegas office concealed the medical order suddenly.

Steven Marx, a computer forensics who worked for the Drug Enforcement Administration at the time of the singer's death, testified that he examined emails on Murray's phone, finding some medical information about a patient named Omar Arnold, one of the aliases Jackson used to get prescription medication.

And a voicemail, which Jackson's former manager Frank Dileo sent to Murray dated June 20, 2009 - several days before Jackson's death, was played in court.

Would you please call me? Dileo asked the doctor, I'm sure you're aware [Jackson] had an episode last night; he's sick … I think you need to get a blood test on him today; we gotta see what he's doing, DiLeo suggested the star was hiding a drug problem.

Elissa Fleak, a coroner, testified that she found abundant drugs and a jug of urine in the singer's bedroom. There was a nearly-empty 20-milligram vial of Propofol on the floor, and an empty bottle of Flumazenil, which is used to treat Benzodiazepine overdoses.

The trial is scheduled to last about four weeks. If convicted, Murray could serve a sentence of up to four years in prison and also lose his medical license.
